Just to add another option to the discussion, OGC has a Geosynchronization specification getting close to being finalize. It uses XML requests from the Web Feature Service - Transactional spec to describe actions on a spatial database such as add, modify, delete. Like CouchDB, it also doesn't specify what to do about conflict resolution. This has to be done with your software smarts.
